Usage of IC 7442¶

# Usage of IC 7442:
ic = IC_7442()
print(ic.__doc__)
This is a BCD to Decimal decoder
BCD Digits are in order of A B C D where pin 15 = A, pin 12 = D
# The Pin configuration is:
inp = {8: 0, 12: 0, 13: 0, 14: 0, 15: 1, 16: 1}
# Pin initinalization
# Powering up the IC - using -- ic.setIC({14: 1, 7: 0})
ic.setIC({14: 1, 7: 0})
# Setting the inputs of the ic
ic.setIC(inp)
# Draw the IC with the current configuration\n
ic.drawIC()
